续上一篇日志< c,golang,java,php,nodejs,python,pypy运算速度粗焅比较>
看到网上已经有人在测试php8,就尝试使用php8运行一下LangTest的代码.
使用了docker来运行
docker run --rm -it \
-v /data/code/LangTest/php:/var/www/html \
-w /var/www/html \
keinos/php8-jit \
./run.sh
php8-jit
run php
end i:1000000000 count:499999999500000000 time:2.9510369300842
php7.2
run php
end i:1000000000 count:499999999500000000 time:26.515455007553
相对于php7.2快了差不多9倍了.
但和c, java, golang等还差得很远.

先把结果抛出来,

run python:
^Tend i:1000000000 count:499999999500000000 time:193.98550415
以上的结果进行了golang和c的性能优化.

这两天idea总是出现不能访问某个类.
尝试过rebuild project,但问题都没有解决.
好吧.然后网上很多文章说要重启.但这里的重启不是关掉重开.而是清理缓存,然后重新启动.
国内的文章实在是太简了.只能通过google找到原来的那边文章.

前几天,调试一个ftp功能,随便把生产的php版本更新到最新.
主产点基本上没有什么问题.但部分小站点却出现了错误.
Trying to access array offset on value of type null
原来这个只存在于php7.4的问题.
好吧.看来我的半年稳定论用改了.变成九个月?1年?
反正还是老老实实的用7.2.
